Description of key information
Waived: Direct/indirect exposure of the soil compartment is improbable.
Key value for chemical safety assessment
Additional information
In accordance with Column 2 of REACH Annex IX, the study does not need to be conducted if direct or indirect exposure of the soil compartment is unlikely. The substance (monomer) is not manufactured within the EU, and is only imported as its reacted (covalently-bound) form in polymers (i.e., polyols) having typically < 0.2% wt. residual unreacted monomer. There is no known or expected mechanism by which degradation of these polymers could result in re-formation of the monomer substance. Therefore, direct and indirect exposures of the soil compartment to this substance are highly improbable. Furthermore, the monomer substance is readily biodegradable, and by definition will not persist in the soil environment.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
